通信行业是增长最快的行业之一，20世纪80年代开始使用的1G蜂窝系统现在已经演进到4G。随着社会的发展，对高数据速率的需求呈指数级增长。通信工程师的典型目标是高速通信，数据传输速率高，信号质量好，因此必须尽可能降低误码率、降低功耗和VLSI实现能力。4G系统确保我们的数据传输速率达到1Gbps，这是SISO系统无法实现的，因此我们选择MIMO系统。本报告讨论了MIMO的各种优点，讨论了Alamouti方案的实现，并对各种信道估计方法进行了讨论和仿真。本文所研究的MIMO系统与传统的SISO系统相比具有显著的优势，目前正在4G蜂窝、MIMO雷达以及其它各种新兴通信技术中实现。

The communication industry is one of thefastest growing industries. The cellular systems started in the 80’s with 1G have now reached to 4G. The growing demand of high data rates areincreasing exponentially with time. The typical goals of a communicationengineer are high speed communication for which the data rate should be high,better quality of signal for which we have to minimize the bit error rate aslow as possible, less power consumption and VLSI implement ability. The 4G system ensures us data rate of 1Gbpswhich cannot be achieved by SISO systems and hence we go for MIMO system. Thevarious benefits of MIMO are discussed in this report. The implementation ofAlamouti scheme is also discussed and then the various methods of channelestimation are discussed and simulated. The proposed MIMO system hasdistinguished advantages over the conventional SISO systems and this is beingimplemented in 4Gcellular, MIMO radar and in various other emerging communication technologies.
